In page Cairo Citadel:

"

In general, the fortress complex is divided into two parts: the Northern Enclosure (where the National Military Museum is located today), and the Southern Enclosure (where the Mosque of Muhammad Ali is located today). The Northern Enclosure was historically reserved for military garrisons, while the Southern Enclosure was developed as the residence of the sultan. There is also a lower, western enclosure which was historically the site of the royal stables of the Mamluks.[1] However, these functional distinctions were largely erased in the 19th century under Muhammad Ali Pasha, who overhauled the entire site and constructed buildings of various functions throughout the Citadel.[2]
